Abstract excerpt

BACKGROUND: The A1 allele of the TaqIA polymorphism (rs1800497) in the dopamine D2 receptor gene (DRD2) has been associated with substance use. It is unclear whether this allele is a marker for an underlying propensity for specifically developing a substance use disorder, or more generally to developing an externalizing psychiatric disorder highly correlated with substance use. It is also possible that DRD2 is...
